Hi all,
i am using C30 compiler for dsPIC30 (i think it basically gcc right?)
i have a problem as i tried to make automatic macro value generation for UART baud rate register.
#define XTAL 7500000U
#define PLL_MULTIPLIER 8U
#define CLOCK_POSTSCALER 1U
#define F_OSC...
i found the cause of the problem. it is called "spurious interrupt". i didnt set the default interrupt vector address register. now it is ok :)
cheers,
hi,
a little explenation:

in short, ehader file is very useful to make modular development, where the applicaiton is divided in to many source codes modules

Hi all,
i am using phytec-LPC2294 board. I met a very stranget behaviour. With my application, everytime there is an error occur on CAN module which generate an interrupt, the program goes back to reset. i am having problem also to find out the cause because when i put break points in the isr...
hi all,
i am using a ar-gcc compiler for my microcontroller board with LPC2104. i want to examine something in the output files (.lst, .map, etc.). i havent found any good reference to understand the content of the file.
yould someon give me a hint?
thanks in advance
Hi all,
I am quite used to program in C, but for OOP i dont have the concept quite deep yet. I have (maybe) a simple question: what is the difference between (function) overloading concept in C and polymorphism in C++? as i noticed, they have almost the same purposes: to provide single...
Hi,
i dont know whether it works with uclinux, but there is a linux emulator called qemu. maybe you want to check it out.

Hi,
building the Linux system from scratch is not impossible. I just finishing a project which is almost the same specification. I did it in 3 months with a very low experience in Linux as I started the project.

Re: PIC or AVR
Hi,
i think it doesnt make anysense to have long discussion about which microcontroller is better in general. it is like asking "which football team is the best?" (you can see my avatar :D) and people will say what their own opinion.
Personally i used to work a lot with AVR, but...
i am not sure about that, i am also a newbee in linux.
but it seems that you have to use C type shell (csh or tcsh) .
you can check your shell using the following command:
ps -p $$
hope this helps:

I am using the X11R6.7.0. and I am planning to do:
- make the shadow directory build using lndir command
- configure the host.def file
- build the X windows:
make CROSSCOMPILEDIR=<PATH_TO_CROSS_COMPILER> World
- install to the CF card (supposed it is mounted on /mnt/cf):
make install...
wow..
never heard of that linux can be ported to MCS51.. i dont know about FreeDOS..
isnt linux much much too big to be put in MCS51?
if you look RTOS for MCS51 try to google it. but i dont think it is possible to port linux there. the smallest linux i ever heard for uC is uClinux.
